Synthetic,spectroscopic, thermal,and structural studies of antimony(III) bis(pyrrolidinedithiocarbamato)alkyldithiocarbonates

An account of the synthesis, spectroscopic, thermal and structural behavior of antimony(III) bis(pyrrolidinedithiocarbamato)alkyldithiocarbonates is presented. The reaction of antimony(III) bis(pyrrolidinedithiocarbamate) chloride with potassium organodithiocarbonate in equimolar ratio yielded the corresponding mixed derivatives of the type (CH₂)₄NCS₂]₂SbS₂COR where R = Me, Et, Pr ⁿ , Pr ⁱ , Bu ⁿ , and Bu ⁱ ]. These newly synthesized complexes have been characterized by physicochemical molecular weight determination, melting points, and elemental analysis], spectral UV, IR, far-IR, NMR (¹H and ¹³C)], thermal TG, DTA, and FAB⁺ mass], and structural powder XRD and SEM] studies. Analytical studies leads to purity and structural properties of the synthesized complexes on the other hand powder X-ray diffraction and SEM studies show that multiphase, polycrystalline, and rod-shaped complexes have been formed having nanorange crystallite size and monoclinic crystal system.
